Drill Guide

+++ Update on Sep 29th +++
No one complained/suggested about the license, so I decided to upload all my STL files. I made the base to be able to detach the shafts (clamp version), but I can make a glue version, so that the guide shafts can be mounted on the side and the back if it's requested.

I think I found the original product and the one I bought from Amazon was a Chinese copy.

The original has more good features and the best quality, but the price is really good too.

I found a drill guide from Amazon and bought it. There was no comment about the manufacture, but it was made and shipped from China. It took about 2 months to get it, but I learned a lesson about Chinese quality. It was a piece of junk, the drill chuck was out of center, Z-motion had too much play and since guide rods are aluminum, the motion was not smooth at all.

I bought good quality components from Amaz
